Application lcd July 6, 1911. Serial No. 637,?"

To 7l yiii/mm, it may concern.'

Be it known that I, .f viiiizsoN V. Sealife, a eitizeii ot the 'United States, residing at MeConih, inthe County et'l lfilv'e and Statie of Mississii'iiiii, have invented oei-tain new and useful .l'nii'iroveinents in Gage-Cocks, et whieh the 4following is a Si'ieeilieation.

My invention relates to improvements in gage eoelvjs and relers partirularly to that elasi; ift' cooks used upon steam boilers for determining the water level.

The leading object ot.' in v invention is the. prt'iviaii'in ot" a device oit.' this character whieh will ohviate the difficulties and dieadvautagt-S; ol eoels new in general use, and nuire i'iartieularly my invention is designed as an inipio'veuient upon the gage enel; patented h v nie @ctoher ZlS, ltilt), No. 973,074-, and whieh l have found to he unsatisfactory in a 'f i'ninor details. The present invention is designed to overcome these objections and hroadlir Stated my improvement, resides in the provision of a sleeve and eonipressihle veiled spring slidably mounted. in a sleeve eap or easing', and this construction replaeesv the separate. skeleton portion or ineinher ol in v 't'ornier patent..

M v invention further eonsistsriu` the pro-v vision oit' a device et the character described whieh will en'ihody novel features o't eonsti-notion and combination-0f parte 'tor serviee, siulistantially as disclosed herein, and in order that 'my invention may he fully undia'stood and its many advantages appre- :eiated I have illuatrated in the accompanying drawings a. practical einhodinuint of uri7 device in whichd Figure fl represents a longitudinal seetional view of `the complete device. Fig. 2 represei'itn a detail view ot` the sleeve eap or casing. Fig. 8 represents a detail view in section of the slidable sleeve and tlang'e which forms one oi the mosty ini portant features ol niy invention, and liip". -f-li'ep'i'e-;eiitf an end elevation o't the rini or i'lanfre shown in Fig'.

In the drawings in Whieh Similar eharae- 'ters of reference denote corresponding parts in the several views: The numeral 'l design .nates the liody portion or inenihor ol in v gage eoelv', ot' Cylindrical Shape., and having' the sei'ewdln'eaded end l'oi' engagement with the eori'espoiuling ,arrow-threada ot' the steam heiter. llxtending i'eiitraltv through ,im portion `t is theevliiulrieal hoi-e or i551.) Ii having at lnie end the opening-1t;

and at itsl other end the valve seat fi, having the tiee end ot a evlindi'ieal valve rod ti ground to 'lorin a 'truste-conical portion T adapted to he snugly seated upon the said valve Lseat. l l.\'tendin;1r downwardly there- `troni and at substantiallyY right angles to the hotly portion l is tht.I hraneh or nipple S, having` the axial openingl t), eoininuiiieating willi the valve seat and passage, the passage 2l, valve seat valve rod t3 and nipple S heingr ineased in the socket or joint:I l0. Arranged 'lorwardljv ot saidsoeket lt) is the e.\'ternall vy threaded portion ll, engaging' the eorrespoiuhng internally threaded cylindrical easing' lL). havingT the nut lil, adapted to ref-rive a ivrint-h oi' other tool for removal', and arranged in said canine' '1*.2 is a `suitahle t'orni ot parking ll. adapted to he held in plat'e hv a washer l5. .Wranged iii said evlindrieal easing' lL is a y'sleeve lt'i internally threaded to engage the externally threaded portion Vli ol said valve rod t, and said sleeve ltl tias integrally l'oi'uied on one end the tlaage or iini lb. whieh is adapted t0 engage vthi` aaid washer l5 to retain saine in plaee against` the parking'. Mounted in an annular ehanihi-r lf) in said evlindrieal easinjL' 'l2 and entirely Surrounding the sleeve It is a oiled `|`spring' 20, ha ving' one end ahnt tint;l againsty 'the rini or flange 'ti on Said sleeve and its` other end retained liv thel 1nivai'dtv -;\'teiidiii; llangg'es. 2l o'l the .said CaS- ingl l2, Frein this eonstriu-tion it will be seen that the .said sleeve tt and llaiige 1S are adapted to he nioved longitiulinall)Y along the threaded portion 17 o't the valve rod 6 and 't'ui'theriuoi'e that the coiled spring' 2() retains the valve. in proper position. The i'iin or eollar 't8 is provided with a notch 0r hert 1S vloi'nied upon its outer edge into whirh is adapted to he ei'ig'aged a lug' or rib t9 projeetving troni the inner wall ot the housing' or easing. This construction prevents the revolution ot the sleeve 1.6 when the valve stein is rotated. 'lhe forward end ot" the valve rod 0 is mounted in the hand wheel :'32, hy means ol` which the valve rod inay tie turned.

in operatii'in it; will he Seen that upon the rotation ot` the valve rod (3 and the sul'isequent. unseati'nlgr thereof, the water will he lree to pass through the opening "t `into the .opening il, and when the valve is seated upon the valve seat 5, the flange or riin 18 ot the sleeve lt' out o't engagfeinei'it with the 'washer l5 .in the cylindrical easing 12,

and that the coiled sprin- 2O retains the said sleeve and hence the Valve rod in its seated position upon the valve seat 5. lt. will also he noted that rotation of the valve rod Will cause the automatic grinding of the'trustoconical portion 7 upon the seat 5,. and furthermore that all Wear betweenthe valve seat and portion 7 will he taken 'up by the spring Q0 and sleeve 16.

From the foregoing it- Will he apparent that l have provided a device for the purpose stated which will overcome the objections to the gage cocks in presentusage; which will be ot extremely simple and inea; pensive construction; and which Will be entirely practical and efficient from every point. of View.

I claim:

l.' In a gage oook, the combination with a housing and a threaded valve rod, of a threaded sleeve carried loy said rod, a nut termed integral upon one end ot said sleeve, a Washer mounted in said housing forward of the integral nuton the sleeve, and a coiled spring interposed between the 'sleeve and the housing and intermediate the said nut and the rear Wall of the housin'.

2. In a gage coclnthe combination With a housing and a threaded valve rod, of a threaded sleeve carried by said rod, said sleeve consisting of a longitudinally extending portion having a nutormed integral therewith and disposed at right angles thereto7 a Washer carried by the valve rod :ton ward of the integral nut and adapted to abut against said nut7 and a coiled spring entirely surrounding the longitudinally eX- tending portion of the sleeve and intermediate the said nutl and the rear wall of the honi ng.

3. ln a gage cock, the combination With the body portion haring the central passage therethrough7 the 1valve seat,the nipple communicating with and at rightl angles to said valve seat, the interiorly threaded cylindrical housing the uut carried thereby, the parking arranged in said housing at its tor- Ward end, the 'Washer disposed rearwardly of the packing and adapted to'retainsame in place, vthe longitudinally extending externally threaded rotatable valve stein, the interiorly threaded sleeve carried thereby, the integrally formed nut carried by said sl fave at its toiyvardend1 the coiled spring surrounding the said sleeve and stein intermediate 'the rear Wall of the housing and the 'integrally formed nut ot the sleeve., and the hand Wheel at the rear end ort the stem for rotating same and unseating the valve from its seat.

in testimony whereof l aiiix my signature in presence oit two Witnesses.
